6 Claims. (01. 101-107) This invention relates to printing devices and more particularly to a portable printing device for use in applying musical characters to blank sheets.

' An object of this invention is to provide a device of this character which is so constructed that a composer or the like can readily impress the desired characters on the blank sheets of paper used for music in such a manner that the composer or person copying music will not be required to use a pen to draw out each character.

Another object of this invention is to provide a device of this character which is exceedingly 7 simple in construction, embodying relatively few parts so that it will not readily get out of order and can be manufactured at a relativelysmall cost.

A further object of this invention is to provide in a device of this kind means to yieldably hold the impression cylinder with the raised characters thereon out of contact with the sheet of paper until the entire device has been forced in the direction of the papers.

A still further object of this invention is .to

5 provide in a device of this character a means whereby the desired ink may be applied, the ink being placed on a ribbon which is disposed in the yieldable impression member and normally maintained out of contact with the paper so that 30 the ribbon will not smudge the paper as the device is being moved along the surface of the sheet.

The above and various other objects and advantages of this invention will in partbe described "35 in, and in part be understood from the following detail description of the present preferred embodiment, the same being illustrated in the accompanying drawings, wherein:--

Figure 1 is a detail side elevation of a device 40 constructed according to an embodiment of this invention showing the device in applied position;

Figure 2 is a similar view taken from the opposite side of the device from that shown in Figure 1;

45 Figure 3 is a sectional view taken on the line 3-3 of Figure 1;

Figure 4 is a plan view of the blank for the housing;

Figure 5 is a detailed perspective view, showing 50 the manner in which the device is used in impressing characters on a ruled sheet.

Referring to the drawings wherein like numerals of reference designate corresponding parts throughout the several views, the numeral I0 55 designates generally a housing which, in the presplate I 8, secured to a hub l9, journaled on a shaft or bolt 20, extending axially and transversely through the housing Hi. This cylinder 11 comprises an impression cylinder and is provided on the peripheral edge thereof with raised characters 15 2| of the type used in the recording of music, itbeing understood that these characters 2| may be notes of different values and other indicia used in the recording of music.

A second housing, generally designated as 22, 20

is disposed at one side of the housing l0 being integral therewith and comprises a side plate 23,

a bottom wall 24, and an end wall which extends partially about the side wall 23. The end wall 25, as shown in Figure 4, is provided with 25 opposed lugs 26, one of which is adapted to engage in the side wall I I of the main housing and the other adapted to engage in a notch 21, provided in the outer side wall 23. A ribbon 28 is mounted on a spool 29 which is rotatably carried 30 by the shaft or bolt 20 within the housing 22 and this ribbon 28 may be of the usual character used in typewriters, or the like.

The bolt 20 is provided at one end with a head 30 and a yieldable washer 3| is interposed between the head 30 and the side wall l2. The other end of the bolt or shaft 20 is threaded, as at 32, and a wing nut 33 is threaded onto this .end of the bolt. By means of the wing nut 33, the desired tension may be placed on the two side walls H and I2 so that the hub l9, secured to the plate l8, will be frictionally held against turning but permitted to turn when desired.

The ribbon 28 is threaded through a pair of alined eyes 34, carried by the ends of the forked or bifurcated portion l6. These eyes 34 are formed by bending the ends of the arms of the bifurcated portion backward to form loops or eyes. In this manner the ribbon 28 is disposed against the lowermost character or indicia 2| and the eyes 34 hold the ribbon 28 off of the surface of the lined sheet 35.

In order to determine the position of the characters 2| on the periphery of the drum or cylinder I1, I have provided a substantially frustro- 56 conical shaped member 36 which opens through the outer or forward side of the cylinder l1 and the inner surface of this member 36 is provided with indicia Zla of a type similar to the corresponding indicia 2| on the surface of the cylinder or drum IT. This member 36 may be formed as a separate part and then welded or otherwise secured to the flange or drum I! or may be made integral therewith.

In the use and operation of this device, the drum I! is turned so that the desired character 2| is disposed in confronting relation to that portion of the ribbon 28 disposed between the arms of the fork IS. The correct position and the correct character may be determined by glancing at the indicia 2la on the inside of the frustro conical member 36. The forked member I6 is then placed on the surface of the sheet 35 and the housing It) then grasped between a thumb and forefinger whereupon the housing It] is pressed toward the sheet 35, thus forcing the lowermost character 2| to contact with the ribbon 28 and impress this character 2! upon the surface of the sheet 35.

It will be understood that the eyes 34 and the ribbon 28 disposed within the eyes will serve as a guide means to facilitate placement of the characters in the desired position relative to the lines 3? provided on the sheet 35.

It is, of course, understood that various changes and modifications may be made in the details of construction and design of the above specifically described embodiment of this invention without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claims.

I claim:-

1. A device as set forth comprising a housing having an opening in a wall thereof, a drum rotatable in the housing and having a portion thereof projecting through said opening, raised characters on the periphery of the drum, a character inking means, a resilient arm carried by the housing for resiliently holding the characters away from a sheet of paper, and a pair of guide eyes carried by said arm on opposite sides of said drum for holding the inking means in operative position.

2. A device as set forth comprising a housing having an opening in a wall thereof, a. drum rotatable in the housing and having a portion thereof projecting through said opening, raised characters on the periphery of the drum, a character inking means, a resilient arm carried by the housing for resiliently holding the characters away from a sheet of paper, guide means for said inking means carried by said arm, and means for frictionally holding the drum against rotation.

3. A device as set forth comprising a housing having an opening in a wall thereof, a drum rotatable in the housing and having a portion thereof projecting through said opening, raised characters on the periphery of the drum, a char- 5 acter inking means, a resilient arm carried by the housing for resiliently holding the characters away from a sheet of paper, and means carried by said arm for holding said inking means in operative position. 0

4.

6. A device as set forth comprising a housing having an opening in a wall thereof, a drum disposed within the housing, a shaft carried by the housing and extending through the drum to rotatably support the drum in the housing, raised characters disposed on the periphery of the drum, a second housing secured to said first housing at one side thereof, an inking, means in said second housing, said inking means including a flexible strip extending outwardly through said second housing, means for frictionally retarding ro tation of said drum, a resilient arm carried by the housing and a forked member integral with said arm and provided at the ends thereof with eyes, said flexible strip being disposed loosely through said eyes and extending transversely of the opening in the housing.
